Lost key, can I temporarily bypass ignition switch?

[JakeByTheSea]

I have a 1999 Bayliner Sierra 2855 with 7.4L MPI Bravo 3, and Quicksilver 3000 control box. I misplaced the key and I was looking to temporarily run the boat to show someone. I'll figure out long term replacement or solution another time. I posted picture of switch, is there a way I can touch to wires to together to crank boat, and leave running for 10 minutes? Looks like red wire on pin labeled "B", yellow with red stripe on pin labeled "S", and the purple and blue/yellow wires on pin labeled "I"

B=Battery, jump to I=Ignition, Then jump to S=Start. Or just go to a local parts store and get a new switch.

If you're looking to sell it why not just replace the switch?
